            <description>The &quot;URL&quot; must point to the location of the processing script. If a proxy is required, define &quot;HTTPProxy&quot; for the proxy address.

Customization:
- &quot;graphWidth&quot; and &quot;graphWidth&quot; can be defined for the image size
- &quot;showLegend&quot; can be defined to show or hide the legend of the graph
- &quot;subject&quot; can be defined for a customized subject for the mail message
- &quot;periods&quot; and &quot;periods_headers&quot; can be defined for displaying multiple periods of the same graph, or
- &quot;period&quot; and &quot;period_header&quot; can be defined to display a single graph

The html.template and plain.template files can be adjusted (TWIG format).
